(TIMP-2)x(IGFPB7) to Predict Acute Kidney Injury (AKI) in Aortic Surgery

(TIMP-2)x(IGFPB7) as Early Renal Biomarker for the Prediction of Acute Kidney Injury in Aortic Surgery - an Observational Study (TIGER)

New biomarkers that predict the development of renal dysfunction in patients with aortic surgery are urgently needed. The investigators investigate whether urinary (TIMP-2)x(IGFBP7) predicts postoperative Acute Kidney Injury and/or need for Renal Replacement Therapy (RRT) in patients after aortic surgery (including EVAR).

Inclusion Criteria:

• Patients in need of emergency or elective abdominal aortic surgery (infra- or suprarenal clamping or EVAR) are eligible for study inclusion.

Exclusion Criteria:

• Patients unable to give informed consent
• Age < 18
• Patients not speaking German or French.
